If I couldn't drive a jeep, I'd look at a forester. But whereas I'm fine with the little v6 in the large jeep, having driven underpowered subarus for too many years, that forester would need to be diesel, or turbo, or anything that did not remind me of the slug-o-wagons I'd owned B4.
Much respect to the 2.2 and 2.5 boxers. Well-designed powerplants!
